In this paper, the learning algorithm of iterative training combined with Radiationl Basis Function (RBF) is used to construct a neural network, through which the traffic signal control strategy can be obtained to provide a more efficient traffic signal control scheme for the traffic problems at intersections. Compared with the traditional traffic control strategy, the neural network in this paper reduces the average delay time of vehicles. According to the characteristics of mobile traffic flow detection information, a road condition probabilistic neural network discriminant method based on mobile traffic flow detection information is proposed, by analyzing the relevant factors of road conditions, and also considering the influence of the signal control intersection red light on the travel time delay of the vehicle, by combining the RBF algorithm to improve the probability neural network, according to the field survey data, the prediction of the neural network is derived more accurately. By comparing the predicted results, the average delay time of vehicles at intersections is reduced, and the hidden danger of traffic safety is reduced.
